MACHINE FOR MANUFACTURING GLASSWARE.

SPECIFICATION forming part of Letters Patent No. 584,665, dated June 15,1897. Application filed November 16, 1896. Serial No. 612,830. (Nomodel.)

To all whom, it may concern.-

leit known that I, CHARLES EDWIN BLUE, of Wheeling, in the county ofOhio and State of West Virginia, have invented certain new and usefulImprovements in Machines for the Manufacture of Glassware; and Idohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit pertains to make and useit,-reference being had to the accompanyingdrawings, which form part of this specification.

My invention relates to improvements in machines for the manufacture ofglassware, and pertains to mechanisms comprising a pl nrality of moldsin which the several operations necessary to construct a bottle, jar, orother vessel is respectively perform ed, whereby a finished article isproduced at each movement of the mechanisms.

The object of my presentinvention is to provide amachine having the modeof operation and advantages hereinafter pointed out, producing a machinesimple in construction, P6".

liable in operation, and capable of rapid manipulation.

Fig. 7 is an enlarged topplan view of jaws used in connection with the mechanism for withdrawingthe primary mold from its operative position. Fig. 8 is a sectional viewtaken on the line 8 8 of Fig. a.

Fig. 9 is an enlarged sectional detail view of the cylindcrvalve.

Referring n'ow to the drawings, 1 indicates a base, which is preferablysupported upon wheels, as here shown, and this base carries a hollowhousing 2. Supported upon and su rrounding the housing 2, intermediateits ends upon a ring 82, is a table This table is capable of rotationaround the housing 2 and carries a plurality of molds, including,preferably, a charging, a blowing, a fixing, a removing or discharging,and a refixingor arranging mold numbered, respectively, 4, 5, 6, 7, and8 in Fig. 4.

Each of the molds is provided with a primary bottom 7 and a secondarybottom 8. The function of the primary bottom is to have the glasswarecharged therein and then pressed and then removed from its operativeposition, and the secondary bottom 8 supplementing it for the purpose offorming a blowing-bottom, as indicated clearly in Fig. 2 of thedrawings, all of which is well understood by those versed in the art.

The table carries depending casings or re-' ceptacles 20, in which theprimary bottoms 7 extend when they are out of operative position, thelower ends of the casings orhousings 20 being provided with lips 47,adapted to arrest and support the primary bottomsin their lowerpositions, as clearly illustrated in the drawings.

Passingthrough the lower end of the housing is an operatingshaft 24,carrying a crank 23, to which the lower end of a pitman 22 is connectedin any suitable manner. The up per end of the pitm an 22 is suitablyconnected to a vertically-movable head 10, supported and movablevertically within an extension 9 of the housing 2, the said extensionforming a slideway and a support for the head 10. The extension orslideway 9 is provided at its lower end with a laterallyextendingarm andat its upper end with a corresponding laterally-extending arm 2, whichform guides and supports for-the presser-head rod 13. Alaterally-projecting arm 14 is provided upon the head 10, through whichthe presser-head rod 13 passes. Above this arm 14 is .an adjusting-nut16 and beneath it an adjusting nut 17, through the medium of which therod 13 can be adjusted vertically through the arm 14 of the head 10, asmay be desired. An operating-lever 26 is connected with a wheel on thearms at one end of the shaft 24, and the opposite end of the shaft isprox'ided with a counterweighted lever 25, as illustrated clearly inFig. 2. When the operating-lever 26 is actuated, the shaft 24 movesthrough a portion of a revolution and through the medium of the crank23'and, pitman 22 moves the head up or down, according to the directionin which the operating-lever is moved. The lower end of the rod 13carries the presser-head 13 and also the usual spring mechanism justabove the presser-head, and which is so well understood by those skilledin the art that reference and description thereof in this application isconsidered unnecessary.

Situated upon the base 1 at a point under the fixing-mold S is acylinder 29, carrying a piston-rod 28, with a piston-head thereon, theupper end of the said rod 28 being adapted to engage the lower end ofthe primary bottom when the table or carrier is at rest. A pipe 27communicates with the lower end of this cylinder and also with a block33, having a longitudinal opening, as clearly shown in Fig. 6, the otherend of the block communicating with any. source supplying air throughthe medium of a pipe 36. Passing vertically through the block is avertically-movable valve 31, which is normally held up by means of aspring 32, surrounding the upper projecting end thereof. This valve issituated immediately below the operating-shaft 24, and the shaft 24carries a cam 30, adapted to engage the upper end of the valve. Thisvalve has a passage 34, adapted to aline with the opening in the block33, so that when the valve is depressed, as illustrated in Fig 6, air ispermitted free access to the lower end of the cylinder 29, which forcesthe rod 28 up, carrying with it the primary bottom 7. hen the pitman ismoved downward by the oscillation of the shaft 24 to lower thepresser-head and perform the pressing operation, the valve 31 isdepressed and air admitted into the cylinder 29, as just stated. hen,however, the shaft 24 is oscillated through the medium of the handle 26to elevate the presser-head after the pressing operation, the cam isrotated out of engagement with the valve 31, which permits it to moveupward, bringing the opening 35 in alinement with the opening in theblock This upward position of the valve permits a lateral escape of theair through the block 33 as the piston-rod 28 and its head movesdownward in the cylinder under their own weight. From this descriptionit will be seen that while one primary bottom of a mold is moved upwardautomatically by the pressing action the pressing of the glass is beingperformed in another, blowing may be going on in a third mold, and theopening and the removal of the finished glass article from still anothermold may be simultaneously going on.

Situated on the base 1 at a pointbelow the pressing-mold 5 is a cylinder37, carrying a piston-rod 38, having a piston-head movable within thecylinder 37, the upper end of the rod having a head 45, provided withcatches 46, the said head having a lateral opening 91, for a purpose tobe presently described. A

pipe 39 has its opposite ends communicating respectively with the upperand lower ends of the cylinder 37, as shown in Fig. 1, and air is fed tothis pipe 39 through the medium of a pipe 40, communicating with anysource of air-supply, said pipe 40 having regulating valves 41, by meansof which the flow of air to opposite ends of the cylinder can beregulated. A red 42 has its upper end adapted to engage openings 44 inthe under side of the table 3, and this red is adapted to move downward,being held normally upward through the medium of a spring 92. This rod42 has at its lower end a foot-piece 85, by means of which it may bedepressed. The rod passes through the air-communication to the cylinderand is provided with openings, so that when the rod is in its upwardposition air is admitted to the lower end of the cylinder and permittedto escape atits upper end, and when the rod is depressed air is admittedto the upper end of the cylinder and allowed to escape at the lower end.

Situated adjacent to each of the primary bottoms 7 is a holder 21, hereshown in the form of a latch. i/Vhen the'bottom is forced upward throughthe medium of the rod 28 in the cylinder 29, the holder automaticallydrops inward by gravity under the primary bottom and holds it in theupward position ready to be charged when it reaches the position 4 inFig. 4, and it is sustained in this upward position until it reaches thepressing position 5 in Fig. 4. When it has reached this position andafter the pressing-head has been depressed and the pressing operationperformed, the operator places his foot upon the foot-piece of the rod42, which first separates the jaws 72, through the medium of a wedge orcam 43, secured to the rod 42, and which engages the jaws when the rodis depressed and forces them apart. These jaws 72 are provided with anopening 73 through which the rod 33 passes,the rod having a shoulder torest upon the upper side of the jaws, so that when the rod has beenforced upward it is held in this upward position for sustaining theprimary bottom. The jaws having been separated by the downward movementof the rod 42 and the upper end of the said rod thrown out of engagementwith the openin g 44, the operator then, by means of the handle 80,moves the table around until the next mold is brought to position forpressing, at which time the upper end of the rod 42 will automaticallydrop into its opening 44, thus automatically admit-tin g air to thelower end of the cylinder 37 and automatically forcing upward the rod33, the rod carrying a valve which controls the primary bottom at thepressing-point. The upper end of this red, as before stated, carries ahead 45, provided with catches 46, and these catches automatically graspthe headed projection upon the lower end of the primary bottom. Thedepression of the rod 42 causes the air to force the rod 38 downward,which carries with it the primary bottom, and when in this downwardposition the table may be revolved, the headed projection 90 passing outof the lateral opening 01 in the head 45. The upward movement of thehead 45 engages the holder or supporting-latch 21 and throws it out ofengagement with the lower end of the primary bottom, so that the primarybottom is no longer locked in its upward position, but is permitted tomove downward with the rod 38.

The presser-head rod 13 supports an essentially Ushaped arm 60, with itsends 61 encircling the rod, and this U-shaped arm or frame 60 isprovided at its center with a laterally-projecting arm 62, through whicha hollow rod or pipe 58 freely passes.

The lower end of this rod 58 is provided with a ball-joint 56 in theupper end of a portion of the blower-head 52. The ball-joint 56 is heldin position by a plate 57, as clearly illustrated in Fig. 5, and theportion 52 carries a valve 53, projecting downward within the cavityformed therein. The blower-head proper, 50, has an upward extension 51,movable vertically within the cavity or recess formed in the portion 52,and the valve 53 has a stem which is made hollow at its upper portionand communicates with the opening made in the ball joint 56. An opening54- is made laterally through the valve-stem, which permits the air topass laterally therethrough and above the upper end of the extension 51of the blower portion of'the blower-head 50. When the head 10 is movedupward for carrying the presser-head out of the mold, the arm 62 of theU-shaped frame 60 engages an adjustable stop 63 upon the pipe or hollowrod 58, moving the rod upward, and in this upward movement the lowerportion of the blower-head drops down and the valve 53 is seated. Thisposition cuts the air off, and the air above the upper end of theextension 51 serves to seat'it firmly and to more perfectly cut off theescape of any air. When the head 10 is lowered for the purpose ofpressing the glass in the 1n old, the lower portion 50 of theblower-head resting upon the upper end of the mold, it forces downwardthe portion 52, thus unseating the valve 53 and permitting air to escapearound its stem into the mold through the portion 50, thus blowing orexpanding the pressed glass previously placed therein, as illustrated inFig. 2. The hollow pipe or rod 58 is provided with a weight 64, so thatwhen it is per mitted to drop it will be sure to unseat the valve 53 byforcing the portion 52 down upon the extension 51 of the blower-headseat 50.

flhrough the medium of the adjustable stop that all manipulations of theprimary and secondary bottoms areperformed completely and wholly whilethe table is at rest. This is a great advantage in that it reduces theamount of power in operating the machine. That is to say, where anymeans is used to cause the movement of either the secondary or theprimary bottoms or of both of them, or of controlling them in any mannerthrough the medium of the movement of the table, it requiresconsiderable power to move the table and makes it extremely laboriousupon the operator. This is avoided absolutely in my construction, theoperator only being called upon to move the presser-head up and downthrough the medium of the'lever 26 to depress the foot-piece and to turnthe table. As the turning of the table does not perform any function inthe way of operating any part of the machine, it is readily turned withbut little labor and is a great saving upon the operator. By means ofthe mechanism herein described the laborious part of the operation isperformed by air-pressure and not by the operator, since the head 10 andthe lever 26, as well as the pitman 22, are counterbalanced through themedium of the weighted lever or arm 25 upon the shaft 24, thus enablingthe pressing operation to be easily accomplished at the expense of butlittle labor.

In Fig. 3 I illustrate a modification of my machine by which thesupporters or controllens 21 are omitted, and likewise the cylinder 29and its cooperating mechanism. In this instance the primary bottomremains down .until it reaches the pressing position, when the rod 42,moving upward automatically by dropping in its opening 44, admits air tothe lower end of the cylinder, which carries the primary bot-tom upwardin position to be charged, and after the charging operation the pressingis carried on as described in relation to Fig. 1. In this instance theupper end of the head 45 will have a curved groove like unto the groove91 in Fig. 8, except the groove will extend entirely through the head,so that as the table is rotated the headed projection upon the lower endof the primary bottom will move into the said slot and be engaged by thecatches carried by the head. When the pressing has been performed, adownward movement of the rod 42, through the medium of the pedal orfoot-piece 85, ad mits air to the upper end of the cylinder, asdescribed in relation to Fig. 1, which causes the primary bottom to becarried downward, when, owing to the fact that the slot extends entirelyacross the head, the table can be rotated and the headed projection 90moved from engagement with the head 45 of the rod 38. This constructionis not so desirable as that shown in Fig. 1, in that the charging isperformed at the pressing-point, thus delaying the pressing until thecharging has been completed. By the construction in Fig. l the charging,pressing, blowing, discharging, and refixing of the bottoms are allbeing performed at the same time, thus enabling the machine to be morerapidly manipulated, as will be readily understood. It will also be orrather the movement of the presser-head rod, controls the blowingmechanism through the medium of the U shaped frame and its arm 62. Thisaccomplishes in a single movement both the pressing and the blowing ofthe glass.

Through the medium of the ball-joint 56 the lower or seating portion ofthe blowinghead 50 is permitted to seat itself at all times perfectly incontact with the face of the mold, which is necessary to accomplish anair-tight joint.

In the lower end of the cylinder 37 is provided a cavity or recess 95,and the lower side or end of the piston-head within the cylinder isprovided with a projection 96. The object of this is to form anair-cushion for arresting the downward movement of the piston-head underthe weight of the primary bottom when air is admitted at the upper endof the cylinder. This relieves the machines of the concussion and jarwhich would otherwise occur.
